 * <p>
 * 地址簿管理 AddressBookController主要开发的功能:
 * <p>
 * A. 新增地址逻辑说明： 需要记录当前是哪个用户的地址(关联当前登录用户)
 * B. 设置默认地址:
 * - 每个用户可以有很多地址，但是默认地址只能有一个 ；
 * - 先将该用户所有地址的is_default更新为0 , 然后将当前的设置的默认地址的is_default设置为1
 * C. 根据ID查询地址
 * D. 查询默认地址:根据当前登录用户ID 以及 is_default进行查询，查询当前登录用户is_default为1的地址信息
 * E. 查询指定用户的全部地址: 根据当前登录用户ID，查询所有的地址列表
